构建失败 Spring 未找到引导插件

Question

I download a repo 'gs-handling-form-submission' from spring.io and now I'm trying to build: gradle build

Following Error has being triggered

 * Where:
Build file 'C:\Users\Username\Desktop\gs-handling-form-submission\complete\build.gradle' line: 11

* What went wrong:
Plugin [id: 'org.springframework.boot', version: '2.4.2'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.springframework.boot:org.springframework.boot.gradle.plugin:2.4.2')
  Searched in the following repositories:
    Gradle Central Plugin Repository

I already added a repo url, changed spring.boot version, added buildscript.repositories() at the first line, even doing that, I can't get to compile.

plugins {
    id 'org.springframework.boot' version '2.4.2'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    jcenter()
    mavenCentral()
    maven {
        url: "https://plugins.gradle.org/m2/"
    }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}

Answer 1

Fixing the build.gradle , removing : url, was possible to build

plugins {
    id 'org.springframework.boot' version '2.6.3'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    jcenter()
    mavenCentral()
    maven {
        url 'https://plugins.gradle.org/m2/'
    }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}
